  The series contains stuff I caught last week while working on some
x86 code. It can be considered a material for fixes or for next,
I'm okay with either, although leaning more towards fixes :P

Notes on patches:
* 0001: I didn't put any "Fixes:" tag since it's not linear. The
        lines changed with this patch came from the initial x86
        KASLR series, but that unconditional jump to the kernel
        beginning already was there. It goes at least from the set
        that brought relocatable kernel support to x86, but this
        is quite prehistoric already and might not look really
        relatable. So up to you whether it needs any.
* 0002: doesn't fix anything, except that having any files listed
        in that whitelist already is an architecture bug :D And
        it wouldn't be convenient to decouple it from #0001, but
        up to you as well.

  x86/boot: robustify calling startup_{32,64}() from the decompressor
    code
